Rnnvns, a fastened and the dotted lines showing an citizen of the United States, residing at adjusted position of the operating member Portland, in the county of Multnomah and when the locking device is released to admit State of Oregon, have invented certain new of opening or closing the transom; Fig. 4 is and useful Improvements in Combined an enlarged detail ofaportion of the sprocket Transom Adjusters and Locks, of which the Wheel, dog cooperating therewith and the f ll i i a ifi ti operating member for moving the dog into The invention is primarily designed to released position, as indicated by the dotted provide means for operating transoms or lines; F 1g. 5 is a horizontal section on the analogous light and ventilating devices 1111c -5 of Fig. 4; Fig. 6 is a detail perhi h are di d t h a h i ht s not spect ve View of the slide and the bracket to be readily or conveniently reached withformlng a mounting therefor; Fig. 7 is an out requiring the person to mount a chair, enlarged sectional view of the shock absorbladder or like device. lng device interposed in the length of the The invention provides operating means operating member; Fig. 8 is a detail perwhich at the same time serves to secure the spective View of the dog constituting the transom at the required adjusted position, locking device which cooperates with the said means being of such structural formasprocket wheel for securing the transom 01' tion as to be readily and conveniently oplike part in the located position. Fig. 9 is erated by a pulling action, the operating an enlarged section of a portion of the member being flexible and adapted in one caslng and sprocket wheel showing more position to admit of locking means coming clearly the manner of mounting the latter. into play for securing the transom or like Corresponding and like parts are referred part in the desired adjusted position and to in the following description and indiwhich when moved to another position recated in all the views of the drawings by leases the locking device, so that the tranthe same reference characters. som may be closed or permitted to open to The numeral 1 designates a transom or a greater extent as may be required in the like part generally employed for obtaining zidjustment thereof. light and ventilation over door ways and The invention, furthermore, has for its at other convenient points in dwellings and object the provision of transom operating buildings generally. A bracket 2 is secured and securing means which maybe applied to to the transom or like part 1 at one end a relatively narrow margin as when an end thereof and at some distance from its hinge of the transom is close to a wall or other connection with the door frame or other projecting part, such application not intercasing surrounding the opening in which fering in the least with the efficiency of the the transom or like part is fitted.

a section 011 the line 38 of Fig. 2 looking A casing 8 is attached to the frame or like to the left, as indicated by the arrows, the part inclosing the opening in which the full lines showing the normal position of the transom is fitted and such casing may be of any construction so as to provide a light and neat appearance and which may be cheaply manufactured and form a substantial housing for the sprocket wheel and cooperating locking device. A sprocket wheel 9 is mounted in the casing 8 and is preferablyhollow so as to receive a spiral spring 10 which is utilized to facilitate the opening of the transom. The spring 10 is connected at its outer end to the outer portion of the sprocket wheel and at its inner end to one of a number of tongues 11 partly cut from a side wall of the casing and bent inwardly at a right angle and forming a support for the spring 10. The sprocket wheel 9 has a hub 9" through which a sleeve 9 passes. This sleeve 9 is a trifle longer than the hub 9 to prevent binding of the sprocket wheel 9 between the sides of the casing. A fastening 9 passes through the sleeve 9 and connects the sides of the casing. The operating member 7 preferably consists of a chain, the links of which are of suchshape and size as to cooperate with the teeth 12 of the sprocket wheel and thereby positively rotate the same so as to place the spring 10 under tension when the transom is closed. The operating member 7 passes over the sprocket wheel thence down in the rear thereof so as of a dog 13 arranged to engage one or an other of the teeth 12 of the sprocket wheel. The dog 13 is provided at one end with a I weight 14 and at its opposite end with a projecting tooth 15 which is adapted to engage any one of the teeth 12 of the sprocket wheel, as indicated by full lines in Figs. 3 and 4, thereby holding the transom in the adjusted position. A sleeve 16 is formed with the dog as a part thereof and projects beyond opposite sides thereof and is adapted to receive a pin 17 upon which the dog is mounted. The weighted end 14: of the dog is made rounding to insure the ready passage thereover of the operating member 7. The projecting end or tooth 15 of the dog constitutes a stop to limit the movement of the dog when the same is moved by the operating member to clear the teeth of the sprocket Wheel and thereby prevent any interference of the dog with the free movement of the sprocket wheel either in the opening or theclosing of the transom. The

lower wall of the casing 8 is provided with an opening for the operating member 7' to pass through and to receive a portion of the dog 13. The projecting end or tooth 15 of the dog is adapted to engage the part of the casing adjacent the outer end of such opening and thereby limit the movement of the do as indicated most clearly by the dotted lines, in Fig. 4c.

The parts of the transom operator and fastener are disposed so that when the transom is closed the pin 5 will engage the rear portion of the sprocket wheel, as indicated most clearly in Fig. 3. In this position the projecting end 15'of the dog 13 engages a tooth 12 of the sprocket wheel and holds the same against the tension of the spring 10, thereby securing the transom in locked position. When it is required to open the transom the lower end of the operating member 7 is swung outward away from the door frame and is thereby brought into engagement with the weighted end of the dog 13, thereby pressing the rear end of the dog upward and forward with the result that the toothed end 15 of the dog is moved away from the sprocket wheel into the position shown by dotted lines in Fig. l, thereby clearing the teeth of the sprocket wheel. The operating member 7 being held in the position indicated by dotted lines in Fig. 3 and the pull thereon being relaxed to admit of the sprocket wheel 9 turning in an anticlockwise direction the pin 5 in engagement with a tooth of the sprocket wheel is moved upward and forward thereby positively opening the transom and moving the same to such a position that it will open by its own weight after the pin 5 has cleared the sprocket wheel. It will thus be understood that the spring 10 is utilized as means for positively opening the transom and moving the same past a dead point so that the transom will open by its own weight after the pin 5 has cleared the sprocket wheel. When the transom has opened to the required distance it is made fast by bringing the lower portion of the operating member 7 into vertical position, thereby releasing the weighted end of the dog 13. When the weighted end of the dog 13 is relieved of the pressure of the operating member 7 it drops thereby elevating the toothed end 15 of the dog and bringing the same in position to engage a tooth of the sprocket wheel which latter is prevented from further rotation in an anticlockwise direction, thereby holding the transom in the desired position by the cooperation of the operating member 7 and teeth of the sprocket wheel. If it be re quired to open the transom farther the lower end of the operating member 7 is drawn out Ward away from the door frame, thereby releasing the dog by exerting an inward and upward pressure upon the weighted end thereof and by permitting the operating member to move upward the transom lowers. On the other hand should it be required to close the transom the lower end of the operating member is pulled upon thereby rotating the sprocket wheel in a clockwise direction, the teeth 12 of the sprocket wheel riding upon the toothed end 15 of the dog 13. When the transom is entirely closed the pin 5 passes over the upper portion of the sprocket wheel and to a point in the rear thereof, as indicated in Fig. 3.

The operating member 7 may be provided in its length with a shock absorber or yieldable stop 1.8 which relieves shock in the event of the transom dropping suddenly to the limit of its opening movement. This shock absorber may be of any construction and as shown comprises a support 19 and an eXpansible helical spring 18. The upper end of the spring 18 is arranged to engage the casing 8 when the transom is at the limit of its opening movement. The lower end of the spring 18 engages a shoulder 20 at the lower end of the support 19. A cord or other connection 21 is attached to the lower end of the support 19 and extends within convenient reach to be pulled upon when it is required to operate the device.
